The property builderClassTemplate does not exist. Did you maybe forget to declare it?

                str_replace('generator/templates/static', 'src', $file['path']),
                $this->flysystem->read($file['path'])

It seems like $this->flysystem->read($file['path']) targeting League\Flysystem\Filesystem::read() can also be of type false; however, League\Flysystem\Filesystem::put() does only seem to accept string, did you maybe forget to handle an error condition?
